Refer to TS Only UEs that have a valid subscription, are authenticated and authorized for PS service in the attached location are allowed. Issues for CT1 TR The following CSG related functions are defined: Stage 3 for Mobility management based on MIP v4. Stage 2 for BB3: The copyright and the foregoing restriction extend to reproduction in all media. In addition the MME may off-load a cross-section of its subscribers with minimal 3hpp on the network and users e. Four different behaviours of emergency bearer support have been identified as follows: The configuration of a UE for low access priority and Access Class are configured independently of each other.

References are either specific identified by date of publication, edition number, version number, etc. A network node may invoke one or more of the following mechanisms based on the indicators received in signalling from UEs or forwarded by other network nodes: It is assumed that the mechanisms described in this entire clause are designed by Stage 3 in a manner that allows extensibility and forward compatibility.

The emergency bearer contexts shall not 3ggpp changed to non-emergency bearer contexts and vice versa. It is up to RN implementation how it ensures no UE is connected. Created from version This mechanism provides preferential access to UEs based on its assigned Access Class.


In addition, to protect the network from overload the MME has the option of rejecting NAS request messages which include the low access priority indicator before rejecting NAS request messages without the low access priority indicator see clause 4. A term defined in the present document takes precedence over the 3gp of the same term, if any, in TR For discrepancies between this overview clause and the detailed procedure and function descriptions the latter take precedence. Direct Transfer … 5b.

To avoid that large amounts of 2341 initiate deferred requests almost simultaneously, the MME should select the Mobility Management back-off timer value so that the deferred requests are not synchronized. This is to minimize unneeded signalling after the Mobility Management back-off timer expires. If all of the PDN connections for the UE need to be relocated, the MME may initiate the “explicit detach with reattach required” procedure as specified in clause 5.

Specific situations that require setting the RRC establishment cause to emergency are described in TS Roaming architecture for local breakout, with visited operator’s application functions only 4. Version created with approved When establishing emergency bearer services with a PDN GW and dynamic policy is used, according to clause 4.

The load re-balancing can off-load part of or all the subscribers. Architecture aspects of EHNB.

Delete Subscriber Data functional procedure – can’t find in 3GPP : LTE

Home routed traffic NOTE 1: No records to display. The serving PLMN provides this indication based e. During Tracking Area Update procedures, including a 2341 as part of a handover, the target MME ignores any mobility or access restrictions for UE with emergency bearer services where required by local regulation. The MME does not treat certificate-based and preshared key-based solution differently.


Use of a too short timer for the more preferred PLMN search can both prevent the failed network from recovering, and, impose more load on the local competing networks.


Earthquake and Tsunami Warning System. The selection is based on network topology, i. This means the Serving GW selected for such subscribers may need to support both GTP and PMIP, 234001 that it is possible to set up both local breakout and home routed sessions for these subscribers.

The contents of the present document are subject to continuing work within the TSG and may change following formal TSG approval. General Versions Responsibility Related. All UEs are allowed. Stage 2 for Dedicated Core Networks. A UE that can not be authenticated will be rejected.

The MME should not release all S1 connections which 23410 selected to be released immediately when offloading is initiated.

With minimal impact on network and the user’s experience, the subscribers should be off-loaded as soon as possible.
